Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a device for quickly cleaning and blowing a taphole mud sleeve. Background Art

[0002] During the production process of a blast furnace, slag and iron are periodically discharged from the hearth through the taphole. Before tapping, the integrity of the taphole mud sleeve must be checked to ensure that the nozzle of the mud gun machine can fully contact the mud sleeve when plugging the taphole after tapping is completed, to avoid mud leakage causing difficulty in plugging the taphole or even the taphole being unable to be plugged. The taphole mud sleeve must be intact when plugging the blast furnace taphole to ensure that the mud gun head and the mud sleeve are tightly combined during plugging, so that the refractory mud can be smoothly driven into the taphole, ensuring the taphole depth and continuous and stable production of the blast furnace. When the taphole mud sleeve is damaged or has slag accumulation, in order to ensure the safety of plugging, it is necessary to immediately use special tools to make the mud sleeve and ensure that the mud sleeve surface is flat. If slag accumulation or damage occurs in the mud sleeve during production, the scraping device must be used in time to clean the mud sleeve and remake the mud sleeve to meet the tapping requirements. Therefore, there is an urgent need for a device that can quickly clean the residue of the taphole mud sleeve to improve operating efficiency and reduce equipment wear. Utility Model Content
